The fact is that BFG (which I have) 7900gt's oc to nearly the same core and memory speeds (550/1600) as the GTX and in SLI, blow both single cards completely out of the water and for the exact same price!!! 2 BFG 7900gt's = $650. Regardless of what people say here on this forum, SLI provides a profound performance increase with 7900GT (G71) GPU's!!
